To all whom tmc/y oon-corn:

Be it known that I, ULi'ssns S. Gr. A'rHnY, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Resnforced- Concrete Floor Construction, of ivhich the following is a specification containing a full', clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.l

My invention relates to reinforced concrete iioor construction, the object of my invention being to provide an improved means for supporting longitudinal and transverse reinforcing bars on a temporary floor `and to provide recesses in such supports Whereby 'a bond Wire passed around said reinforcing bars and engaging in said recesses Will prevent movement of the parts relative to each other. Afurtherobject being `to, rovide a support and means .whereby rein orcl ing bars of various sizes may be secured to prevent movement relative to each other.

For the'above purposes my invention con! sists in ,certain novel features of the construction and arrangement of parts as will be hereinafter more fully described, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure l is a perspective of one of the supports; Fig. 2 is a plan illustrating the support attached to crossed reinforcing bars: Fig. 3 is a sectional elevation of a section of concrete flooring showing the crossed reinforcing bars supported on a temporary floor and the bond Wire for securingthe bars and supports immovable relative to each other; and, Fig. 4 is a perspective of the support showing a section of bond Wire arranged to secure reinforcing bars of 'one size and in dotted linesa'bond Wire for securing bars of a different size.

Referring by numerals to the accompanying drawings; 1 designates a substantially, inverted U-shaped support having vertical Yend portions 2, an upper horizontal portion 3 and diagonally disposed recesses 4 formed in the side margins of the horizontal portion 3. vlerforations 4a are formedin the horizontal portion, oppositely' disposed in relation to each other and to the recesses 4. This support is preferably made of a single piece: of sheet metal Which is struck and sanie manner as when engaging formed complete by one operation of a machine. rlhis support is positioned on the ,temporary iiooring 5 underneath the transverse reinforcing bars 6 at a point where the longitudinal reinforcing bars 7 cross the bars 6, the reinforcing bars T being positioned over and in av plane above the bars 6, thus temporarily supporting the bars to prevent sagging thereof between their fixed ends and allowing concrete to iiow beneath them. l/Vhen in such position the bond wire 8 is passed underneath' the supporti engaging in the recesses 4, when employed in connection with reinforcing bars from one half to one inch in thickness, and passed around the bars 6 and 7 and its ends united. Con-- crete is then filled in upon the temporary flooring' 5, around the support and reinforcing bars thus making a reinforced concrete floor. temporary'iloorv is removed. When the support is employed on lesser sized bars a bond wire is passed throughthe perforations 4EL and secured around the bars in the in the notches and on larger sized bars.

By the employment of the supports as shown, assuming the reinforcing bars and temporary floor to be in position, the supports are placed upon the temporary floor and not secured thereto, at points underneath the bars 6 Where the'bars 7 cross over them, thus taking up all of the sag of such reinforcing bars to place them. in horizontal alinement relative to each other. The bond After the concrete is set the. I

Wires are then secured around the bars and supports either through the perforations or engaging in the recesses in the supports to prevent slipping or movement4 of the Wire, thusretaining the bars in fixed positions relative to each other. After all of the bars have been united where they cross each other, concrete is filled in upon the temporary floor around and over the reinforcing bars and their supports which concrete, when set together with the reinforcing bars, forms a fire proof and practically indestructible construction, the temporary floor 5 being removed after the concrete `is thoroughly dry and set.

It is obvious that my improved support maybe used in reinforcing pillar and beam construction or, in fact, in any place Where consiruced oi s single piece of sheet inezil cesses and po.

being openings J orined in iiie suppor die,

hidden and embedded in the reinforced con crete construction. li; is obvious 'further that the support may be to secure i reinforcing` hars of various sizes.
